TQ all whom t may cof/wcm.'

Be it known that I, ALFRED R. WILSON, a citizen of the United States of America, residing at Detroit, in the county of layne and State of Michigan, have invented cer tainnew and useful Improvements in G ar Roofs, of which the following is a specification, reference being had therein to the ac companying drawings.

.The invention relates to car roofs of that :type in which the ca/'rlines extend above the roofing sheets and form the supports and weather-profongcaps therefor. One of the objects of the vinvention is-to obtain a construction in which the carline flange above the roofing sheets has aninwardly or down- -wardly extending portion terminating adjacent to the sheets to more completely prevent moisture Vvfrom getting access to the side edges of the sheets. A further object is to obtain a construction in which the carline -has down-turned ends which extend over. the down-turned flanges at the ends of the roofing sheets and provide clearance therefor. Other objects of the invention reside in the novel .arrangements and combinations iof parts as more fully hereinafter set forth.

ln the drawings;

AFigure l is a top plan view of the car roof, with parts broken away;

Figure 2. is a Icross section on the line v2 2 of Figure 1;; v 1

Figure 3 is a side elevation partly in section of a portion yof the roof;

Figure 4: is a cross-section onthe line 4-4 of Figure l; v

Figures 8, 9 and'lO are respectively a" side elevation of, a top plan view of, and

a `,cross section lthro-ugh a car roof showing ia modified bracket for securing the carline to the .side plate;

.Figuren ll is a perspective view of the,

modified bracket.

A are Ythe carlin'es of the .upper 'edges of therwebs these `carlines 'being arched transversely of the car and having the down-turned end portions B .overlapping .the sides .of the car. C are the T-section `having i the webs A and the lateral flanges A2 at:v

-rooling sheets also-have thevraised 'reinrelatively movable rooiingsheets extending from eaves to eaves of thecar roof and provided at their side edges with the upwardly-extending flanges C arranged below the lateralflanges of the carlines and' at their ends with the downturned flanges C2 overlapping the sides of the cars. The carlines A are secured to the sideplates D and have the end portions of ltheir webs A cut away atl E adjacent to the inner .sides Y ofthe side plates, the intermediateportions of the webs extending therebetween. Brackets F arranged in pairs and upony opposite sides lof the webs A are secured thereto by the rivets F vand are" also secured-'tov the iFnner sides of the side plates D by thebolts j The roofing sheets@ are supported inter mediate the eaves of the car roof by the purlins G which are formed in sections Gr extending between the webs A of the carlines. The sections are supported -by the plates H, which are secured to the carlines by the inverted U-clips H', and the nuts H2 threadedly engaging the ends of the legs of the clips, the bases of the clips passing approximately throughthe neutral axis of the carlines so that the latter are not materially weakened. The ends of the sections Gr are preferably recessed 'at G2 for the re! ception of the bases ofthe clips andfrhave the bores Gstherethrough for the legs of the' clips, the arrangement being such that lateral `movement of the sectionsV is lprevented. l

For4 the purpose of weather-proofing the car roof-the lateralv flanges A2` of the carlinesA are curved' downwardly and the upwardly-extending flangesv C of the roofing sheets terminate `in the lateral portions C3"v in engagement with the. lateral flanges A2 of the carlines. The upwardly-extending `flanges are spaced from the webs .A ofthe roof', the lateral vflanges A2 'ofthe carlines terminate inthe inwardly ordownwardlly lextending portions A3, the low'er edges of" which are lnear 'the roofing sheets. rIhe forcing corrugatio'ns G .which extend longitudinally thereof and Vare locatedV near the .inwardly-extending Vportions A3 lof fthe car-V .the inwardly-extending portions and the ing.

sheets.

The downturned ends B of the carlines have the portions B of the inwardly-eis;- tending portions A3 out away adjacent to the downturned flanges C2 of the roofing sheets to provide clearance therefor, the inwardly extending portions below the downturned flanges extending adjacent to the 'facing D to act as spacers. The downturned ends of the carlines are secured to the side plates D by the bolts F2. To weather-proof the car intermediate the side edges of the downturned flanges C2 the flashing plates I-I are provided between the roofing sheets and the siding and side plates.

vI are running-board saddles, preferably formed ofpressed sheet metal, and comprising the complementary sections I and I2 each of which have the lower foot flanges J resting upon the lateral flanges A2 of the carlines 'and secured thereto, as by spot weld- The edges of these foot flanges eX- tend down the inwardly extending portions A3 of the carlines to embrace the latter,

lwhereby a stronger construction is made poslFigures 5 and 6, the purlin sections G arer secured to the webs A of the carlines by the brackets M to prevent any lateral movement of the purlins relative. to the carlines. The brackets are located upon opposite sides yof the sections and have the flanges IVI adjacent thereto through which the bolts N pass and 'the flanges M2 adjacent to the webs A through which the bolts N pass. The bolts N and N secure the pairs of flanges upon opposite sides of the purlin sections and carline webs respectively This construction besides preventing lateral movement of the purlins, also assists in supporting the purlins upon the carlines.

V In the modified construction of roofing sheets, shown in Figure .7, the sheets C in addition to having the upwardly-extending flanges C and the lateral portions C3, whichVVK contact with 4the lateral flanges A2 of the carlineS, have theV outwardly and upwardly inclined portions @connecting the flanges C and the lateral portions C3. These outwardly and upwardly inclined portions Q permit greater relative movementbetween the roofing sheets and carlines besides giving greater flexibility to the roofing sheet edges to retain the lateral portion G3 of the sheets in engagement with the lateral flanges A2 of the carlines.

In Figures 8, 9, l0 and ll the means for securing the web A of the carline A. to the side plate comprises the bracket l? preferably formed of sheet met-al and having the U-shaped portion P for enclosing a portion of the web A and also having the laterallyextending flanges P2 lying adjacent to the side plate D and secured thereto by the bolts F2, which also secure the downturned end Bof the carline. `The U-shaped portion P of the bracket has the apertures Q therein in registration with apertures R in the web A through which suitable securing means pass, such as the rivets S for-'rigidly securing the bracket to the carline.

lhat I claim as my invention, is:

l. In a car roof', thecombination with a T-carline with its flange' at the upper edge of the web terminating in inwardly-extending portions, of roofing sheetsy weatherproofed by saidcarline 'and having downturned flanges at the eaves of the car roof, said carline flange also having downturned portions at the eaves, the inwardly-extending portions of the flange being out away adjacent to the downturned flanges of the sheets to provide clearance therefor and having their lower end below the ends of the sheets to provide spacing means.

2. In a car roof, the combination with the side plates at opposite sides of the car, of a T-carline extending thereacross and having` its web extendingbetween said side plates and its flange downturned at the ends beyond said side plates, and means for securing said web and downturnedv flange por'- tions to said side plates. 'i

3. In a car roof, the combination with the side plates at opposite sides of the car, of a T-carhne extending thereacross and having its web extending between said side plates and its flange downturned at the ends beyond said side plates, brackets upon the inner sides of said side plates and secured to said web, and a common means for securing said downturned flange portions and bracketsto said side plates.

`et. In aV ear roof, the combination with a carline having)` a web and a laterally-extending flange, of a relatively-movable roofing sheet having a resilient upwardly-extending flange near said web, a lateral portion in lsliding engagement with said carline flange,l and an upwardly and outwardly inclined portion connecting saidupwardly'extending Llange and lateral portion.'A i. y

5. In a carroof, the combination with a T-carline having a web, a substantially horinl zontally extending flange at the upper edge of the web, and downwardly extending portions at the opposite edges of said flange, of relatively movable roofing sheets having v upwardly extending flanges normally spaced from said web and terminating in substantially horizontal portions slidably engaging said flange, the contacting bearing surfaces of said substantially horizontal flange and roofing sheet portions having relatively 10 large areas, said downwardly-extending por- ALFRED R.
